Characteristics of Adult Caretakers of Children and Youth Served by an Urban Child Welfare Agency

The child welfare system of the early 1990s was marked by the proliferation of home-based services. Research on the effectiveness of various home-based interventions indicates results have been equivocal. The need to make explicit the specific characteristics of the adults and children targeted for home-based services, particularly families from diverse cultural backgrounds, has been identified as a critically needed contribution to the literature. In this study, the characteristics and service utilization experiences of adults and families served in an urban, home-based, child welfare program was examined. The results are discussed in relation to findings on the characteristics and experiences of adults and families served in other settings. Implications for future research and service delivery are discussed.     

Child, Family and Case Characteristics: Links with Service Utilization in Physically Abused Children

We investigated the relationships between child, familial, and case characteristics and mental health and medical health care service utilization by physically abused children. Participants included 26 parents or caregivers of 37 Medicaid-eligible children who had substantiated cases of physical abuse. Children whose female caregivers reported a greater number of stressors were more likely to receive mental health care. Furthermore, children not living with the maltreating caregiver were more likely to receive medical health care services. Results are discussed in terms of factors that may account for these links, and the similarities of these findings with those of service utilization in general and clinical child samples.     

The Role of Cardioprotective Avoidance Beliefs in Noncardiac Chest Pain and Associated Emergency Department Utilization

This study examined cardioprotective avoidance beliefs and general panic/agoraphobia variables among 45 Emergency Department patients with a primary complaint of noncardiac chest pain (NCCP) in the absence of coronary artery disease or other medical explanation. Cardioprotective beliefs about the dangerousness of work and physical activity were assessed with the Fear-Avoidance Beliefs Questionnaire (FABQ). Additional measures assessed complaints of cardiac distress and panic, anxiety sensitivity, panic-related beliefs, agoraphobic avoidance, and depressive symptoms. Hierarchical regression analysis indicated that cardiac distress symptoms are a function of panic symptoms and cardioprotective beliefs concerning both physical activity and work, with 62% of the total variance explained. The predictors also explained 57% of the variance in Emergency Department utilization, which was significantly related to cardiac distress symptoms, number of illnesses, and work-avoidance beliefs. Neither outcome was related to demographics, depression symptoms, general anxiety sensitivity, general panic cognitions, or agoraphobic avoidance. Results suggest that current behavioral understandings of NCCP might be advanced by further examination of cardiac-specific avoidance beliefs and behavior and the potential role these factors play in both symptom experience and medical utilization.

Flow,performance and moderators of challenge-skill balance

The concept of flow is briefly reviewed and several theoretical and methodological problems related to flow research are discussed. In three studies, we attempted to avoid these problems by measuring the experience of flow in its components, rather than operationally defining flow in terms of challenge and skill. With this measure, we tested the assumption that experience of flow substantially depends on the balance of challenge and skill. This assumption could only be partially supported, and, as expected, this relationship was moderated by the (perceived) importance of the activity and by the achievement motive. Furthermore, flow predicted performance in two of the three studies.

Observation can be as effective as action in problem solving

This study discusses findings that replicate and extend the original work of Burns and Vollmeyer (2002) , which showed that performance in problem-solving tasks was more accurate when people were engaged in a non-specific goal than in a specific goal. The main innovation here was to examine the goal specificity effect under both observation-based and conventional action-based learning conditions. The findings show that goal specificity affects the accuracy of problem solving in the same way when the learning stage of the task is observation-based as when it is action-based. In addition, the findings show that, when instructions do not promote goal specificity, observation-based problem solving is as effective as action-based problem solving.     

Expertise acquisition as sustained learning in humans and other animals: commonalities across species

Expertise acquisition may be a universal attribute of animals. In this study data on foraging efficiency, or expertise, was compared for four species: honeybees (Apis mellifera), oystercatchers (Haematopus ostralegus), chimpanzees (Pan troglodytes), and humans (Homo sapiens). Polynomial regression models were constructed to investigate the relationship between age and foraging efficiency. There was a similar expertise–acquisition function between age and foraging efficiency across species, best described by a quadratic equation. The peak of performance was reached, in all cases, before the average age of death but well after reaching physical maturity and the percentage of lifespan devoted to the skill was more than 10% of the species-typical lifespan.     

The relative influence of advice from human experts and statistical methods on forecast adjustments

Decision makers and forecasters often receive advice from different sources including human experts and statistical methods. This research examines, in the context of stock price forecasting, how the apparent source of the advice affects the attention that is paid to it when the mode of delivery of the advice is identical for both sources. In Study 1, two groups of participants were given the same advised point and interval forecasts. One group was told that these were the advice of a human expert and the other that they were generated by a statistical forecasting method. The participants were then asked to adjust forecasts they had previously made in light of this advice. While in both cases the advice led to improved point forecast accuracy and better calibration of the prediction intervals, the advice which apparently emanated from a statistical method was discounted much more severely. In Study 2, participants were provided with advice from two sources. When the participants were told that both sources were either human experts or both were statistical methods, the apparent statistical‐based advice had the same influence on the adjusted estimates as the advice that appeared to come from a human expert. However when the apparent sources of advice were different, much greater attention was paid to the advice that apparently came from a human expert. Theories of advice utilization are used to identify why the advice of a human expert is likely to be preferred to advice from a statistical method. Copyright © 2009 John Wiley & Sons, Ltd.     

Cognitive Ability and Personality Predictors of Training Program Skill Acquisition and Job Performance

Two important issues in the training process concern (1) the relative impact of cognitive ability and personality traits on the ability to acquire skills, and (2) whether training skill acquisition predicts subsequent job performance. We used a sample of 9,793 trainees to address these questions and were able to compare those who succeeded on the job with those who did not succeed on the job. We found that some personality factors positively correlate with skill acquisition and that skill acquisition can predict the level of subsequent job performance.     

Occupational specialty congruence: New data and future directions

The present research examined the relationship between within-occupational congruence and satisfaction, and attempted to integrate hypotheses and findings of prior studies with the conceptual implications of occupational specialty congruence. Correspondence between vocational interests within occupations and specialty choice has shown higher correlations with satisfaction than with congruence (Assouline & Meir, 1987). Occupational specialty congruence was derived by comparing preferred functions with the actual functions characterizing a given occupational specialty. In the present study, involving 120 computer software professionals, occupational specialty congruence correlated approximately .45 with satisfaction, using core job function dimensions. Specialty change within occupation, rather than occupational change, may help in cases of poor occupational choice, burnout, or a change in health. Further research should explore the generalizability of the function dimensions employed herein. Identifying core dimensions can aid in designing both career tracks and certification exams.
